Answer:

The complete question is;

What is not one of the ways that angiotensin II increases arterial blood pressure?

Angiotensin II triggers the sensation of thirst.

Angiotensin II stimulates the secretion of aldosterone.

Angiotensin II promotes vasodilation that decreases peripheral resistance.

Angiotensin II prompts the release of antidiuretic hormone (ADH).

Answer : Angiotensin II promotes vasodilation that decreases peripheral resistance.

Explanation:

Angiotensin is a group of peptide hormones (Angiotensin I-IV) that increases the blood pressure by vasoconstriction.  A specialized structure in the kidney called Juxtaglomerular (JG) apparatus regulates blood pressure. It secretes an enzyme known as renin when the blood pressure drops below the normal level. Renin breaks up angiotensinogen, a protein synthesized by the liver into angiotensin I. Angiotensin I enters the bloodstream and is converted into Angiotensin II by Angiotensin-Converting Enzyme (ACE).

Angiotensin II binds to the receptors in the adrenal glands and stimulates aldosterone production. This hormone helps the kidneys to reabsorb salt (sodium). It also causes the constriction of arterioles (vasoconstriction), which results in increased blood pressure. Thus angiotensin II changes the way the blood is filtered and increases the water re-absorption by the kidneys, which results in the increase of blood volume. When the blood volume increases, it causes an increase in blood pressure. Angiotensin II also triggers the sensation of thirst and prompts the release of the pituitary gland’s anti-diuretic hormone (ADH).

Scientists calculated the net primary productivity at two different forest sites. Both forests have the same gross primary produ
Katen [24]

Answer:

The answer is C.

Explanation:

Net Primary Productivity is a term that is used to express the difference between CO2 that is taken in by the plant with photosynthesis minus CO2 that the plant releases.

The two forest sites given in the example may not have the same biodiversity and the same species of plants so we can't be sure of option B.

Again for the same reasons, we can't be sure of option D because we do not know the specific plant species in each forest since they are in different areas.

Option A can be ruled out for the same reasons, the lack of information about the forest sites, since we do not know the death rate of the plants in either of the forests.

Option C can be true because forest A has a higher net primary productivity rate which can be an indication of lower respiratory activity hence lower CO2 production, resulting in the given higher net primary productivity.

I hope this answer helps.

How does nerve impulses travel from one neuron to another?
olga2289 [7]

Answer:

(d) Electrical-->Chemical-->Electrical

Explanation:

A nerve impulse is the transmission of an electrical change along the neuron's membrane from the point at which it is stimulated (synapse). The normal direction of impulse in the body is from the cell body to the axon. This nerve impulse, or action potential, is a sudden and rapid change in the transmembrane potential difference.

Normally, the membrane of the neuron is polarized at rest, which means that the ionic constitution of the medium internal to the membrane is different from the external medium, which generates different electrical charges in one medium and the other, so this difference, ie , the potential during rest is negative (-70 mV). The action potential thus consists of a rapid reduction of membrane negativity to 0mV and inversion of this potential to about + 30mV, followed by a rapid return to values slightly more negative than the resting potential of -70mV.

Nervous impulse or action potential, therefore, is a phenomenon of an electrochemical nature and occurs due to changes in the permeability of the neuron membrane. These permeability modifications allow ions to pass across the membrane. Since ions are electrically charged particles, changes also occur in the electric field generated by these charges.

Thus, we can say that the correct answer to this question is: Electrical -> Chemistry -> Electrical

In flies, red eyes (r) are dominant to brown eyes (r). a heterozygous fly is crossed with homozygous recessive fly.
nadezda [96]

<u>50%</u>  of offspring will have brown eyes

Explanation:

A heterozygous individual will have the genotype <em>Rr </em>while an individual who is homozygous recessive will have the genotype <em>rr.</em> A cross between the two will result in offspring with phenotype <em>Rr</em> and <em>rr</em> in the ratio of 1 : 1. This can be observed from the Punnet square attached.  The same is the case for the phenotype. The ration of brown eyes to red eyes will be approximately 1 : 1
